Cisco offers packet voice solutions that offer architectural and protocol flexibility, including the choice of H.323 [International Telecommunications Union (ITU) - T Recommendation H.323], Media Gateway Control Protocol (MGCP), and Session Initiation Protocol (SIP) for signaling and call control. In particular; H.323 and SIP are often compared and contrasted with each other. The focus of this paper is how to integrate SIP into existing H.323 networks. This paper addresses current techniques available to address issues regarding the interoperability and coexistence of H.323 and SIP in packet telephony networks.
